Melvyn Bragg and guests Justin Champion, Susan Hardman Moore and Diarmaid MacCulloch discuss the ideas of the religious reformer John Calvin - the theology known as Calvinism, or Reformed Protestantism - and its impact. John Calvin, a Frenchman exiled to Geneva, became a towering figure of the 16th century Reformation of the Christian Church. He achieved this not through charismatic oratory, but through the relentless rigour of his analysis of the Bible. In Geneva, he oversaw an austere, theocratic and sometimes brutal regime. Nonetheless, the explosion of printing made his theology highly mobile. The zeal he instilled in his followers, and the persecution which dogged them, rapidly spread the faith across Europe, and on to the New World in America. One of Calvin's most striking tenets was 'predestination': the idea that, even before the world began, God had already decided which human beings would be damned, and which saved. The hope of being one of the saved gave Calvinists a driving energy which has made their faith a galvanic force in the world, from business to politics. Anxiety about salvation, meanwhile, led to a constant introspection which has left its mark on literature.Justin Champion is Professor of the History of Early Modern Ideas at Royal Holloway, University of London; Susan Hardman Moore is Senior Lecturer in Divinity at the University of Edinburgh; Diarmaid MacCulloch, Professor of the History of the Church at the University of Oxford.

Melvyn Bragg and guests Diarmaid MacCulloch, Lucy Wooding and Charlotte Methuen discuss the Siege of Munster in 1534-35.In the early 16th century, the Protestant Reformation revolutionised Christian belief. But one radical group of believers stood out. The Anabaptists rejected infant baptism and formal clergy, and believed that all goods should be held in common. They were also convinced that the Second Coming was imminent.In 1534, in the north-western German city of Munster, a group of Anabaptists attempted to establish the 'New Jerusalem', ready for the Last Days before the coming Apocalypse. But the city was besieged by its ousted Prince-Bishop, and under the reign of its self-appointed King, a 25-year-old Dutchman called Jan van Leyden, it descended into tyranny. Books were burned, dissenters were executed and women were forced to marry. As starvation spread, King Jan lived in luxury with his 16 wives. The horrors of Munster have resonated through the European memory ever since. Diarmaid MacCulloch is Professor of the History of the Church at the University of Oxford; Charlotte Methuen is University Research Lecturer in Ecclesiastical History at the University of Oxford and Lecturer in Church History and Liturgy at Ripon College Cuddesdon; Lucy Wooding is Lecturer in Early Modern History at King's College, London.

Melvyn Bragg discusses the life, works and enduring influence of the medieval philosopher and theologian St Thomas Aquinas with Martin Palmer, John Haldane and Annabel Brett. St Thomas Aquinas' ideas remain at the heart of the official doctrine of the Roman Catholic Church today and inform philosophical debates on human rights, natural law and what constitutes a 'just war'.Martin Palmer is Director of the International Consultancy on Religion, Education and Culture; John Haldane is Professor of Philosophy at the University of St Andrews; Annabel Brett is Lecturer in History at Gonville and Caius College, Cambridge.

Melvyn Bragg and guests Amira Bennison, Robert Gleave and Hugh Kennedy discuss the split between the Sunni and the Shia. This schism came to dominate early Islam, and yet it did not spring at first from a deep theological disagreement, but rather from a dispute about who should succeed the Prophet Muhammad, and on what grounds. The supporters of the Prophet's cousin Ali argued for the hereditary principle; their opponents championed systems of selection. Ali's followers were to become the Shia; the supporters of selection were to become Sunnis.It is a story that takes us from Medina to Syria and on into Iraq, that takes in complex family loyalties, civil war and the killing at Karbala of the Prophet's grandson. Husayn has been commemorated as a martyr by the Shia ever since, and his death helped to formalise the divide as first a political and then a profoundly theological separation.Amira Bennison is Senior Lecturer in Middle Eastern and Islamic Studies at the University of Cambridge; Robert Gleave is Professor of Arabic Studies at the University of Exeter; Hugh Kennedy is Professor of Arabic in the School of Oriental and African Studies at the University of London.

Melvyn Bragg and guests Helen Bond, John Haldane and John Barclay discuss the influence of St Paul on the early Christian church and on Christian theology generally. St Paul joined the Christian church in a time of confusion and wonder. Jesus had been crucified and resurrected and the Christians believed they were living at the end of the world. Paul's impact on Christianity is vast: he imposed an identity on the early Christians and a coherent theology that thinkers from St Augustine to Martin Luther have grappled with. Crucially, Paul is responsible for changing Christianity from a Jewish reform movement into a separate and universal religion.Helen Bond is Senior Lecturer in the New Testament at the University of Edinburgh; John Haldane is Professor of Philosophy at the University of St Andrews; John Barclay is the Lightfoot Professor of Divinity at Durham University.

Melvyn Bragg and guests Andrew Wheatcroft, Claire Norton and Jeremy Black discuss the Ottoman siege of Vienna in 1683, when the Ottoman Empire tried to capture the capital city of the Hapsburg monarchs. The ensuing tale of blood and drama helped define the boundaries of Europe. In June 1683, a man called Kara Mustafa made a journey to Vienna. That a Muslim Turk should come to a Catholic city was not unusual, but Kara Mustafa did so at the head of the Ottoman Army. Vienna was the capital of the Hapsburg Empire and he intended to take it. The ensuing siege has been held responsible for many things, from the invention of the croissant to the creation of Viennese coffee. But most importantly, it has come to be seen as a clash of civilisations, one that helped to define a series of boundaries, between Europe and Asia, Christian and Muslim, Hapsburg and Ottoman, that influence the view between Vienna and Istanbul to this day. But to see the siege as a defining moment in east/west relations may be to read back into history an idea that was not true at the time.Claire Norton is Lecturer in History at St Mary's University College, London; Andrew Wheatcroft is Professor of International Publishing at Stirling University; Jeremy Black is Professor of History at the University of Exeter.

Melvyn Bragg and guests discuss the culture of the Baroque. What do the music of Bach, the Colonnades of St Peter’s, the paintings of Caravaggio and the rebuilding of Prague have in common? The answer is the Baroque – a term used to describe a vast array of painting, music, architecture and sculpture from the 17th and 18th centuries.Baroque derives from the word for a misshapen pearl and denotes an art of effusion, drama, grandeur and powerful emotion. Strongly religious it became the aesthetic of choice of absolute monarchs. But the more we examine the Baroque, the more subtle and mysterious it becomes. It is impossible to discuss 17th century Europe without it, yet it is increasingly hard to say what it is. It was coined as a term of abuse, denounced by thinkers of the rational Enlightenment and by Protestant cultures which read into Baroque the excess, decadence and corruption they saw in the Catholic Church.

Melvyn Bragg and guests discuss the parting of the Red Sea, the feeding of the five thousand and the general subject of miracles. Miracles have been part of human culture for thousands of years. From St Augustine in the 4th century through the medieval cult of saints to David Hume in the 18th, miracles have captured the imaginations of believers and sceptics alike. The way they have been celebrated, interpreted, dissected and refuted is a whole history of arguments between philosophy, science and religion. They have also been used by the corrupt and the powerful to gain their perverse ends. Miracles have been derided and proved to be fraudulent and yet, for many, the miraculous maintain a grip on our imagination, our language and our belief to this day.

Melvyn Bragg and guests discuss Dante’s ‘Inferno’ - a medieval journey through the nine circles of Hell. “Abandon hope, all ye who enter here”. This famous phrase is written above the gate of Hell in a 14th century poem by the Italian poet Dante Alighieri. The poem is called the ‘Divine Comedy’ and Hell is known as ‘Dante’s Inferno’. It is a lurid vision of the afterlife complete with severed heads, cruel and unusual punishments and devils in frozen lakes. But the inferno is much more than a trip into the macabre - it is a map of medieval spirituality, a treasure house of early renaissance learning, a portrait of 14th century Florence, and an acute study of human psychology. It is also one of the greatest poems ever written. With, Margaret Kean, University Lecturer in English and College Fellow at St Hilda’s College, University of Oxford; John Took, Professor of Dante Studies at University College London and Claire Honess, Senior Lecturer in Italian at the University of Leeds and Co-Director of the Leeds Centre for Dante Studies.

Melvyn Bragg and guests discuss the Arab conquests - an extraordinary period in the 7th and 8th centuries when the tribes of the Arabian Peninsula conquered the Middle East, Persia, North Africa and Southern Europe and spread the ideas of the Islamic religion. In 632 the prophet Muhammad died and left behind the nascent religion of Islam among a few tribes in the Arabian Desert. They were relatively small in number, they were divided among themselves and they were surrounded by vast and powerful empires. Yet within 100 years Arab armies controlled territory from Northern Spain to Southern Iran and Islamic ideas had begun to profoundly refashion the societies they touched. It is one of the most extraordinary and significant events in world history that began the slow and profound transformation of Greek and Persian societies into Islamic ones. But how did the Arab armies achieve such extensive victories, how did they govern the people they conquered and what was the relationship between the achievements of the Arabs and the religious beliefs they carried with them?With Hugh Kennedy, Professor of Arabic at the School of Oriental and African Studies, University of London; Amira Bennison, Senior Lecturer in Middle Eastern and Islamic Studies at the University of Cambridge and Robert Hoyland, Professor in Arabic and Middle East Studies at the University of St Andrews
